How to Move Sidebar and Content Area Over

I currently use WordPress to edit my website, however, I can’t figure out how to move the Sidebar and the content page over to the left so it’s in line with the top-navigation menu.

Here’s what I want to do: [url]https://velociteen.com/SS.png[/url]

How do I edit the CSS so this occurs?

Here is the CSS:

body {
margin:0;
padding:0;
background: #cbe86b;
background: url('https://flowersitters.com/wp-content/themes/velociteen/Bubble%20Girl%20Four.jpg'); background-attachment: fixed;
color:#030736;
text-align:left;
font-family: Arial, sans-serif;
font-size:12px;
}

#container{
background:white;
border:0px red solid;
width:825px;
margin:0 0 0px 0;}

#header {
width : 825px;
height : 275px;
margin : 0 0 0 0;
background : url('https://flowersitters.com/wp-content/themes/velociteen/Banner%203.jpg') no-repeat;
}

#wrapper{

margin:0px auto;}

#content {
